Smokeless tobacco use and personality factors associated with smokeless tobacco use were examined in a broad, representative sample of 8th and 10th graders from central and south-central Florida (n = 1413). Current, occasional, or ex-users of smokeless tobacco accounted for 51% of the males and 9% of the females. Smokeless tobacco users, as compared to non-users, had significantly higher Trait Anger, and Angry Temperament and Angry Reaction subscale scores on the State-Trait Personality Inventory, suggesting a possible role in the initiation of smokeless tobacco use. There were no differences in Trait Anger, Anxiety, or Curiosity scores between the three user groups, suggesting that trait personality does not play a role in the maintenance of smokeless tobacco use.
